Relationship between transforming growth factor beta1 and progression of hypertensive renal disease.
2002
In this study the role of circulating transforming growth factor beta1 (TGFbeta1) on progression of renal hypertensive disease has been investigated. Fifty consecutive outpatients with essential hypertension were enrolled and divided into three groups, according to their urinary albumin excretion (UAE). Group A comprised 10 hypertensives with UAEor=20 mg/24 h (normoalbuminuric group); Group B included 21 hypertensives with UAE20300 mg/24 h (microalbuminuric group); Group C encompassed 19 hypertensives with UAEor= 300 mg/24 h (proteinuric group). In all patients UAE by immunonephelometric assay, circulating TGFbeta1 by a solid phase specific sandwich ELISA technique, BUN and creatinine by ro…
Effects of high-dose furosemide and small-volume hypertonic saline solution infusion in comparison with a high dose of furosemide as a bolus, in refr…
2000
Background: Diuretics, have been accepted as first-line treatment in refractory heart failure, but a lack of response is a frequent event. A randomised single blind study was performed to evaluate the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) infusion in the treatment of refractory NYHA class IV congestive heart failure (CHF). Materials and methods: Sixty patients (21 F/39 M) with refractory CHF (NYHA class IV) of different etiologies, unresponsive to high oral doses of furosemide, ACE-inhibitors, digitalis, and nitrates, aged 65–90 years, were enrolled. They had to have an ejection fraction (EF) < 35%, serum creatinine < 2 mg/dl, B…
Left ventricular hypertrophy and geometry in hypertensive patients with chronic kidney disease.
2009
To evaluate the prevalence of left ventricular hypertrophy (LVH) and left ventricular geometry in a group of 293 hypertensive patients with stage 2-5 chronic kidney disease (CKD), compared with 289 essential hypertensive patients with normal renal function.All patients underwent echocardiographic examination. Patients on stage 1 CKD, dialysis treatment, or with cardiovascular diseases were excluded.LVH was observed in 47.1% of patients with CKD and in 31.14% of essential hypertensive patients (P0.0001). We found increasingly higher left ventricular diameters, thicknesses, and mass from stage 2 to 5 CKD. Distribution of concentric and eccentric LVH was not different between the two groups. H…
Biochemical risk indices, including plasma homocysteine, that prospectively predict mortality in older British people: the National Diet and Nutritio…
2010
Predictive power, for total and vascular mortality, of selected indices measured at baseline in the British National Diet and Nutrition Survey (community-living subset) of People Aged 65 Years and Over was tested. Mortality status and its primary and underlying causes were recorded for 1100 (mean age 76·7 (sd7·5) years, 50·2 % females) respondents from the baseline survey in 1994–5 until September 2008. Follow-up data analyses focussed especially on known predictors of vascular disease risk, together with intakes and status indices of selected nutrients known to affect, or to be affected by, these predictors. Total mortality was significantly predicted by hazard ratios of baseline plasma co…
Symptomatology and Diagnosis of Benign Prostatic Hyperplasia
1991
The symptoms of benign prostatic hyperplasia are well known. Diagnosis rests on digital palpation of the enlarged prostate. Objective parameters are laboratory tests, imaging techniques, endoscopy, and urodynamic investigations. Laboratory tests include urinalysis and serum creatinine measurement. Markers are not reliable and the determination of acid phosphatase and prostate-specific antigen is not recommended routinely for patients with prostatism. Imaging techniques are usually restricted to a complete echographic investigation of the entire urinary tract. Endoscopic manipulations are seldom necessary. Uroflow measurements are customarily performed, but the need for a complete urodynamic…
Elastase, myeloperoxidase, nitric oxide metabolites and oxidative status in subjects with clinical stable chronic renal failure on conservative treat…
2009
We evaluated, in a group of 41 CRF undialyzed subjects (29 men and 12 women, mean age 64.1 +/- 11.3 years), some parameters that reflect leukocyte activation (elastase, myeloperoxidase - MPO), plasma NO metabolites (NO(x)) and the oxidative status (lipid peroxidation expressed as thiobarbituric acid-reactive substances (TBARS) and total antioxidant status (TAS). Elastase was determined, on plasma separated from fasting venous blood, as elastase/alpha1-proteinase inhibitor complex. MPO was evaluated employing the Myeloperoxidase ELISA kit. The NO production was evaluated by a micromethod. The oxidation of polyunsaturated fatty acids was evaluated in plasma by detection of the thiobarbituric …
Rats with congenital hydronephrosis show increased susceptibility to renal ischemia‐reperfusion injury
2020
Abstract Many drug candidates have shown significant renoprotective effects in preclinical models; however, there is no clinically used effective pharmacotherapy for acute kidney injury. The failure to translate from bench to bedside could be due to misleading results from experimental animals with undetected congenital kidney defects. This study was performed to assess the effects of congenital hydronephrosis on the functional capacity of tubular renal transporters as well as kidney sensitivity to ischemia‐reperfusion (I‐R)‐induced injury in male Wistar rats. Ultrasonography was used to distinguish healthy control rats from rats with hydronephrosis. L‐carnitine or furosemide was administer…
Immune-unreactive urinary albumin as a predictor of cardiovascular events: The Hortega Study
2019
Background: We aimed to determine if immune-unreactive albumin excretion (IURAE) is associated with cardiovascular (CV) events in a representative sample of a general population from Spain.Methods: We included 1297 subjects (mean age ± standard error 48.0 ± 0.2 years, 48% females), who participated in the Hortega Follow-Up Study. The primary endpoint was incidence of fatal and non-fatal CV events. Urinary albumin excretion (UAE) was measured in spot voided urine, frozen at -80°C, by immunonephelometry [immune-reactive albumin excretion (IRAE)] and by high-performance liquid chromatography (HPLC) [total albumin excretion (AE)]. IURAE was calculated as the difference between HPLC measurements…
Cystatin C and cardiovascular mortality in patients with coronary artery disease and normal or mildly reduced kidney function: results from the Ather…
2009
Aims Chronic kidney disease is associated with increased risk of cardiovascular disease. Cystatin C is a promising marker to reliably mirror renal function. The role of cystatin C in patients with coronary artery disease (CAD) and normal or mildly reduced kidney function is the subject of current investigation. Methods and results In 2162 patients, over the whole spectrum of CAD, baseline cystatin C concentrations were measured. Patients with an estimated glomerular filtration rate of ≤60 mL/min per 1.73 m2 ( n = 295) were excluded. In patients with complete follow-up information ( n = 1827), 66 cardiovascular deaths were registered during a median follow-up of 3.65 years. Logarithmically t…
Urinary albumin excretion and glomerular filtration rate across the spectrum of glucose abnormalities in essential hypertension.
2006
The objective of this study was to assess the relationship between urinary albumin excretion (UAE) and GF across the spectrum of the glucose metabolism abnormalities in a large population of patients with hypertension. The Microaluminuria en Pacientes con Glucemia Basal Alterada (MAGAL) is a multicenter, cross-sectional study that was carried out by 1723 primary care physicians. A total of 6227 patients with essential hypertension (in three groups: [1] normal fasting glucose100 mg/dl, [2] impaired fasting glucoseor =100 to 126 mg/dl, and [3] type 2 diabetes) were analyzed in this substudy. GFR was estimated by using the Modification of Diet in Renal Disease (MDRD) abbreviated equation. A si…
